Hard Drive not being recognized - 0520-AE: IDE Device #0 Error


Josh Stover

My development server (Windows Server 2K) quit working
over the weekend and is displaying the following error
during bootup.

0520-AE: IDE Device #0 Error.

After continuing through the error I get one line at the
top of the screen indicating that the "Operating System
Cannot be Found."

Nothing has changed with the computer since I used it
successfully before the weekend, but for some reason it is
not recognizing the hard drive anymore. I've created a
boot disk and tried to go into disk repairs, but then it
indicated that I didn't have a hard drive. I have also
unplugged an plugged in the cables, and made sure there
are no damages or bad connections. The computer was left
on over the weekend, could a power surge have fried the
hard drive?

Please help.

Hi Josh,

This is a hardware error. Generally, I would suspect that this is a
controller error. Check cables, etc to ensure connectivity with the disk
and if that is in good shape, then either the disk or controller has
hardware problems.
